Can blue light from the screen harm your eyes?
“Blue light” is nothing but short wavelength with high energy emitted from screens
There is no conclusive evidence that it harms your eyes by causing either macular degeneration, cataract, or eye strain
But it is true that it can cause sleep disturbances, especially when these screens are used at night time.
Tips to prevent eye strain:
- The 20-20-20 rule
Relax your eyes for every 20 minutes of computer work, by taking a 20 sec break and looking at objects 20 feet away.
- Adjust your workspace
Make sure your computer screen is at eye level or slightly below it and adjust the contrast and brightness of your screen to match that of the background ambient light
- Give your eye muscles a work out
Do thumb rotations. Hold out your arm straight in front of your eyes with the thumb pointing upwards. Without moving your head, rotate your arm in a big circle and follow the movement of your thumb with your eyes. Repeat 5 times and then do the same with your other arm.
